微藻和巨藻以其在食品和燃料应用中的用途而闻名。近年来，人们对藻类生物质生产生物炭的兴趣与日俱增。生物炭因其催化活性而广为人知，可以生产许多成品，如替代燃料，处理环境废水，并作为农业应用的投入。利用藻类生物质生产替代燃料通常采用三种途径，即生化、化学和热化学技术。近年来，将藻类生物质转化为生物炭的热化学方法主要采用生物炭基催化剂。生物炭在用作潜在催化剂之前必须被活化。因此，本综述提供了生物炭改性的各种活化策略的广泛信息。在替代燃料生产中，人们正在采用不同的活化方法，如物理和化学模式来改性生物炭，以获得高效催化剂。
Microalgae and macroalgae are known for their use in food and fuel applications. Recently, tremendous interest on algal biomass for biochar production has been increased. Biochar are well known for its catalytic activity to produce many finished products such as alternative fuels, treat environmental waste water and act as an input for agricultural applications. Three routes are commonly adopted for alternative fuel production from algal biomass namely, biochemical, chemical, and thermochemical techniques. Recently, thermochemical methods for the conversion of algal biomass to biochar are employed to use biochar based catalyst. Biochar must be activated before used as a potential catalyst. Therefore, this review has given broad information of various activation strategies for biochar modification. Different activation methods such as physical and chemical modes are being practiced to modify the biochar for efficient catalyst in alternative fuel production.
